To all whom tin [6 7]: concern:

Be it known that I JOHN S. CAMERON, a

citizen of the United States, residing at.

Elliott, in the county of Ford and State of Illinois, have invented anew and usefulv door whichmay bereadilyand easily swungv v to a positionexteriorly of the car and supported in such position to permit the car"to be used: for carrying'materialother thangrain.

Another object of the-invention is to provide a door of this characterincluding a plurality of hinged sections which may be.

moved to their activeor inactive positions at the will of the operatorto facilitate the loading and unloading of the car.-

A still further object of the invention is to provide means foradjusting the door vertically to eliminate any possibility of the doordragging on the floor of the car while it is being transferred from aposition interiorly of the car to the exterior thereof, or vice versa.

W'ith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a side elevational view illustrating a grain car doorconstructed in accordance with the invention as closing the door openingof the car.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on line 3 of Figure 1.

Figure 4 is a sectional view taken on line l4 of Figure 1.

Figure 5 is a sectional view taken on line 5-5 of Figure 1.

Figure 6 is a sectional View taken on line 66 of Figure 1.

Referring to the drawings in detail, the reference character 5 indicatesa car Which GRAIN noon.

Application filed. January 6, 1925. -Seria1 No. 862.

is provided with the usual opening 6 normally closed by means ofthesl-iding closure 7 provided with brackets- 8 which support suitablerollers that move along the track 9. Suitable cleats indicated at 10 areprof. -v1ded for holding thcshdm-g closure 7 to its proper position. i

The grain door wh ch forms the essence of the lnvention is indicatedgenerally by the reference character 10, andincludes a pluralityof-hingedly connected sections 11, which sections are suppliedwitlrlocking members 12 that are adapted to swing within;suitablekeepers to lock the sections 11 in;,their active positions.

' ,The lowermost section o fthe grain door is supplied With anop'eningthat is normally closed by; .the hinged closure 13, sliding bolts 14being provided and adapted to engage within keepers positioned inthe'fioor of the car to hold the hinged closure 13 in its closedposition.

Secured to the grain car door are supporting chains 15 that carrybrackets 16 at their upper ends, which brackets have rollers 17 thatmove within the tubular track section 18, the tubular track section 18being formed with a longitudinal slot to allowtho rollers to fit withinthe track section.

This tubular track section 18 is pivotally supported at 19, one endthereof being positioned within the slot 20 of the support 21 so thatwhen the weight of the grain door exerts a pressure on the'outer or freeend of the track section 18, the rear end of the track section 18 willbe held against movement by its contact with the walls of the slot ofthe securing member.

In order that the tubular track section 18 will be held in a position topermit the grain door to be transferred from the track section 18, alatch member 22 is provided and disposed adjacent to the outer end ofthe slot 20 so that as the track section 18 is swung on its pivot, thetrack section will fall behind the latch member 22 to hold the tracksection against movement.

Mounted exteriorly of the car is a track section 24 which is formed witha beveled end 25 adapted to be engaged by the beveled end 26 of thetrack section 18 so that when the track section 18 is moved to aposition as indicated in dotted lines in Figure 6 of the drawings, thebeveled ends 25 and 26 will contact to provide a continuous tracksection and permit the grain door to be moved onto the track section 24-and to a position exterior-1y of the car.

In order that the chains 15 may act to hold the sections 11 ofthe graincar door in a vertical position, hasps 27 are carried by one of thesections 11 and are adapted to pass over the keepers 28, which keepersaecommodate the hook members 29 for securing the hasps against movement.These hasps 27 are provided With offset portions providing clearancesfor the chains,

From the foregoing it will be obvious that due to this construction, thegrain car door may be readily and easily moved to its ac tive position,or moved out of its active position, adapting the car for use intransporting various types of articles.

I claim:

1. In a freight car door, a body portion,

a door opening, a stationary track section mounted exteriorly of thedoor opening, a

track section pivotally mounted Within the body portion and adapted tomove into engagement With the first mentioned track section to form acontinuation thereof, a support extending inwardly from the Wall of thecar and having a slot, one end of the pivoted track section adapted tomove in the slot, a spring member disposed adjacent to the slot andadapted to engage the pivoted track section to lock the pivoted tracksex:- tion against movement, and a movable door section supported on thepivoted track section.

2. In a freight car door, a body portion having a door opening, astationary track section supported exteriorly of the body portion, atrack section pivot-ally mounted Within the body portion, a supportextending inwardly and arranged near the door opening, said supporthaving a slot, one end 01 the track section adapted to move in the slot,means disposed adjacent to one end of the support and adapted to engagethe pivoted track section to hold the pivoted track section againstmovement, and a sliding door carried by the track section.

In testimony that I claim the foregoing as my own, I have heretoafiixed, my signature in the presence of tWo Witnesses.
